Drag-n-Drop: Guest-to-Host fails above 200 MB (Windows)

[Technologov]

With RC2a, it works a lot better.

Host: Windows 7 x64, RC2a
Guest1: Windows 7 x64, RC2a GA
Guest2: Windows XP, RC2a GA
Guest3: Windows 2000, RC2a GA

It mostly works now, both Host-to-guest, *and* guest-to-host, both files & folders.
Problem is: When copying large folders from guest-to-host, It fails. (above 200 MB)

Tried to setup logging, according to doc: https://www.virtualbox.org/wiki/DnDDebug

Some problems with debug: (Win XP guest)

Code: Select all

C:\Documents and Settings\Administrator>setx VBOX_RELEASE_LOG_FLAGS="time tid thread" /M
'setx' is not recognized as an internal or external command, operable program or batch file.
C:\Documents and Settings\Administrator>setx VBOX_VBOXTRAY_RELEASE_LOG "+guest_dnd.e.l.l2.l3.f" /M
'setx' is not recognized as an internal or external command, operable program or batch file.
C:\Documents and Settings\Administrator>setx VBOX_RELEASE_LOG_DEST="file=C:\Temp\VBoxTray.log" /M

Some problems with debug: (Win 7 guest)

Code: Select all

C:\Windows\system32>setx VBOX_RELEASE_LOG_FLAGS="time tid thread" /M
ERROR: The name of an environment variable cannot include an equal sign (=).
C:\Windows\system32>setx VBOX_VBOXTRAY_RELEASE_LOG "+guest_dnd.e.l.l2.l3.f" /M
SUCCESS: Specified value was saved.
C:\Windows\system32>setx VBOX_RELEASE_LOG_DEST="file=C:\Temp\VBoxTray.log" /M
ERROR: The name of an environment variable cannot include an equal sign (=).

That said, this RC2a build is a huge improvement !

override the host's folder of the same name, like "docs" -> "docs", it fails

Alex,
Please explain this better. I am not sure what you actually mean.

[Technologov]

Assume in guest you have folder C:\docs\, and in host you have folder D:\docs\. Copy-paste from guest-to-host folder "C:\docs" to host's "D:\" should overwrite host's docs folder and files. This operation sometimes works, but sometimes fails.

[Perryg]

OK so what does this have to do with DnD? Are you really doing a c&p or are you saying that DnD sometimes fails if the file already exists?

[Technologov]

If you look at the screenshot, you see. It is clearly a DnD issue.

[Perryg]

You know it's easy to refute someone when you already know the answer to a question and they don't. I was trying to understand exactly what it was you were having issues with, but I guess I should just keep to myself. Sorry for any inconvenience I may have caused you. I promise it will not happen again.

PS: I have a theory as to why but that makes little to no difference now.

UPDATE:
Easy to reproduce. try that large files (or folders, above 200 MB). It fails to copy from guest-to-host. Try to copy any CD/DVD *.iso. Silently fails.
